Description
Houthaven used to be a harbour and timber handling area, situated close to Amsterdam city centre, where many wood factories and related companies were located. After a long history of industrial activities, Houthaven is being transformed into a residential area. In total, seven islands are under development, providing space for 2 200 dwellings, 70 houseboats and 50 000 m2 facilities. In the NEXT-BUILDINGS project, 30 000 m2 of net zero-energy buildings were realised within Houthaven in the area named Blok 0. What is special about Blok 0 is that consortia of future residents took the lead in developing this area. In total about 250 dwellings were foreseen, as well as about 700 m2 of other building uses such as ateliers and studios. A collective car parking was realised, and additional parking is possible at some of the plots.
The construction works finished in April 2016 and by June 2016 Blok 0 was almost completely occupied. Part of the project is also the Brede School, which is an excellent example of linking climate neutral building to education. The roof of the school is equipped with a large array of high-performance solar photovoltaic modules. Monitoring devices have been installed in a sample of the dwellings to ensure that useful energy data from the neighbourhood is available; the approach is based on smart meters and web-based data collection.
Demo Site Expected Impact
*The KPIs for the new building are compared with the baseline of a reference building and reference energy suppliers.
Brede School has an overall area of 6000 m2, where the energy supply is provided by photovoltaics and district heating. According to design data, the objective is a reduction of final energy demand by 450 MWh/year, while the primary energy demand is to be reduced by 612 MWh per year and the CO2 by 53 tonnes per year. The integrated photovoltaic is designed to produce 113 MWh/year with a payback of 7 years.
Blok 0 consists of 9 buildings with a total area of 25 400 m2 with the energy supply provided by photovoltaic modules and district heating. According to design data, the final energy demand of the building is to be reduced by 1778 MWh/year, while the primary energy demand is to be reduced by 2844 MWh per year and the CO2 by 611 tonnes per year. The integrated solar photovoltaic modules are designed to produce 270 MWh/year with a payback of 7 years.
